A weed? Maybe not . . .

Erodium cicutarium, April 29, 2021

Common & scientific name
Filaree, Erodium cicutarium

Family
Geranium, Geraniaceae

Location
Weller Curve roadside, 9,000’

Fun, weird, helpful, or little known fact
While most people view (and treat) Filaree as a weed, according to the supremely excellent Southwest Colorado Wildflowers website, “The most eminent 19th century [botanist] John Torrey indicated in 1852, that this plant ‘is widely spread over the western part of North America, from the Rocky Mountains to the Pacific, and is doubtless indigenous.’”

I can’t recommend the above website enough. It is an amazing resource for all who love Colorado’s wildflowers: www.swcoloradowildflowers.com

A dandy, indeed

Taraxacum officinale, April 27, 2021

Taraxacum officinale, April 27, 2021

Common & scientific name
Dandelion, Taraxacum officinale

Family
Sunflower, Asteraceae

Location
Difficult Campground, 8,200’

Fun, weird, helpful, or little known fact

Of Eurasian origin and now virtually everywhere, owing in part to the fact that their seeds remain viable for nine years or more, with a single plant producing more than 5,000 seeds a year. The good news: Dandelions are an important early spring food source for deer, elk, bear, and (maybe) moose?

Microsteris gracilis, May 14, 2021

Microsteris gracilis, May 14, 2021

Common & scientific name
Slender phlox, Microsteris gracilis

Family
Phlox, Polemoniaceae

Location
Difficult Trail, 8,200’

Fun, weird, helpful, or little known fact

Even easier to miss than Oregon boxwood, this tiny wildflower is often lost among other flowers and grasses in dry meadows and forest openings.  It has 5 petals, its leaves and stem are glandular and hairy, and it rarely grows more than a few inches high. It is frequently found growing beside another tiny beauty, Blue-eyed Mary, both of which will reward the hiker who is willing to stop and get low

An early evergreen

Mahonia repens, May 12, 2021

Mahonia repens, May 12, 2021

Common & scientific name
Creeping Oregon grape, Mahonia repens

Family
Barberry, Berberidaceae

Location
Difficult Campground, 8,200’

Fun, weird, helpful, or little known fact

This hardy plant is abundant throughout our area.  An evergreen, it is able to withstand many degrees of heat, cold, and drought, and its leaves turn a beautiful red in the fall (some of which remain red in the spring, as seen in this photo).  The berries are edible, but much more delicious to bears than people!

A hairy problem

Boechera stricta, May 13, 2021

Boechera stricta, May 13, 2021

B. stricta, siliques 9,200’, June 22, 2021

B. stricta, siliques 9,200’, June 22, 2021

Common & scientific name
Drummond’s rockcress, Boechera stricta

Family
Mustard, Brassicaceae

Location
Weller Curve roadside, 9,200’

Fun, weird, helpful, or little known fact

The Boechera genus is notoriously difficult to narrow down to species.  They interbreed, they vary within species, and often it’s the microscopic hairs on their leaves and the angle of repose of their siliques (seed pods) that make the difference.  This rockcress, which is tall and common on the Pass, especially in forests and at higher elevations, can be identified by the pick-axe hairs on its basal (ground-level) leaves, and its erect, stem-hugging siliques.

How good are your eyes?

Collinsia parviflora, May 13, 2021

Collinsia parviflora, May 13, 2021

Common & scientific name
Blue-eyed Mary, Collinsia parviflora

Family
Snapdragon, Scrophulariaceae

Location
Weller Curve roadside, 9,000’

Fun, weird, helpful, or little known fact

This tiniest of flowers—“parviflora” is Latin for “small-flowered”—will test your eyes (or prescription), but will reward you with its intricate, unusual shape and lovely blue and white petals.

Dozens of flowers in one

Packera tridenticulata x neomexicana, April 29, 2021

Packera tridenticulata x neomexicana, April 29, 2021

Common & scientific names

Threetooth ragwort, Packera tridenticulata X New Mexico groundsel, P. neomexicana

Family
Sunflower, Asteraceae

Location

Weller Curve roadside, 9,400’

Fun, weird, helpful, or little known fact

This flower is most likely a cross, i.e, a hybrid, between the two species named above, with its basal leaves having three lobes (“teeth”) and the plant having a hairy, cobwebby appearance overall (like the neomexicana species). The Packera genus’s family, the Sunflower family, is considered the most highly evolved of all flowering plants: what appears to be one “flower” actually consists of many tiny flowers aggregated together in a flower head consisting most commonly of ray flowers (the “petals”) and disk flowers (the “button” in the middle). This aggregation strategy is thought to attract more pollinators.

Look for me low to high

Noccaea montana, April 27, 2021

Noccaea montana, April 27, 2021

Common & scientific name
Wild candytuft, Noccaea montana

Family
Mustard, Brassicaceae

Location
Difficult Trail, 8,200’

Fun, weird, helpful, or little known fact

This ubiquitous flower is one of our earliest bloomers.  It can be found from the valley floor in Glenwood Springs in early April to the highest peaks on the Pass in July.  Like all mustards, it is edible, but less bitter than most.

Mertenisa fusiformis, April 27, 2021

Mertenisa fusiformis, April 27, 2021

Common & scientific name
Spring bluebells, Mertensia fusiformis

Family
Forget-me-not, Boraginaceae

Location
Difficult Trail 8,200’

Fun, weird, helpful, or little known fact

This charming genus starts small in the spring at lower elevations with Mertensia fusiformis (pictured), shows up similarly small in the alpine in late June as M. lanceolate/virides, and goes big (like 6-feet big) in mid-summer as Mertensia ciliata.

Claytonia Difficult 8,200' 4.27.21.jpg

Claytonia lanceolata, April 27, 2021

Common & scientific name
Spring beauty, Claytonia lanceolata

Family
Purslane, Portulacaceae

Location
Difficult Trail, 8,200’

Fun, weird, helpful, or little known fact
Wherever you find this cheery, candy cane-striped, white flower, you’ll know the snow just melted there. Spring beauty is sometimes called “Indian potato” because its corm—the enlarged, bulb-like base of its stem under the soil—apparently tastes like potato when cooked. I say “apparently” because I haven’t personally tried them. I prefer ogling them to eating them (and I’m lazy).
